Grow bonsai like you want and perfect your techniques in regards to your feelings. However, im certain that you and me have already seen a bonsai tree considered a masterpiece and found something you could have done different. I respect the work of bonsai masters and some do innovate and create trends in the bonsai community. No need to copy the buy bonsai tree instructions manual when you do something, add to it and innovate. This is what forms your signature as an artist. What you feel inside is what it is important. Some have already achieved great results at their respective art form and they have invented or have taken the recipe to do the art to a step above what as been done so far.
